Installation process.
4.1. Norms and recommendations :
In order to meet the safety requirements is necessary to meet the following:
 At least two people are needed to unpack, move and install the pellet
stove. Be careful not to damage the covers of the stove or the stove itself.
 During transportation you need to take in count the information provided
on the package;
 The moving and placing of the stove needs to be done with proper
equipment, following the safety requirements.

If lifting equipment is used (cranes, forklifts), do not let anybody to stay
close to them;
 In case of using ropes during transportation, take in count their strength
and condition;
 During transportation keep the stove as straight as possible; do not tilt it
too much;
 During unpacking of the stove be careful not to damage the side covers of
the stove or the stove itself;
 After unpacking, take out of the burning chamber all the accessories (if
there are any). Also take out all elements used for safe transportation of
the stove (pasteboard, cardboard, plastic);
ATTENTION: Keep all packing materials out of reach of children.
Throw them away in the designated for that purpose places.
4.2. Norms and recommendations
Basic requirements during installation of hot air stove of series “Pony”.
 The room, dedicated to install the stove, should be supplied with fresh air
supply duct, necessary for optimal combustion process as well as room
ventilation. Place the stove where it will be easily checked, maintained or
repaired.
PROHIBITED is installing the stove in bedrooms, bathrooms and rooms in
which is installed other heat source without a vent (open fire place for
instance).
Page. 21/61
 For model “Pony PS9D” – the room, which will be supplied with hot air
for heating, should be connected with the room, where the stove is
installed, with the so called return flow duct. It is highly recommended
the total length of the hot air flow duct not to exceed 3 meters, in order to
sustain optimal air flow conditions. The material of the hot air flow duct,
however, is important – it should be fire-proof (for example made of
aluminum or carbon steel) and the pipe could be straight-surfaced or
corrugated. In order to obtain optimal operation of the heating system, it
is highly recommended to prepare a project by a specialized company for
the heating systems with all the local details considered;
 Installation and service procedures should be performed by authorized
qualified and certified personal ONLY;
 The stove needs to be installed on a floor with required strength and fireresistance. In case of not meeting these requirements you need to choose
other place for installing the stove or to take the necessary actions in order
to improve the place for installation in order to meet the requirements.
Most often the stove is installed on fire-proved floors with size larger than
the stove itself so safety operation is ensured and possibility of fire is
taken to the minimum and also provides easy access for cleaning and
maintenance. The minimum size of the fire-proved floor needs to be
150mm from the sides of the stove and at least 300mm in front of the unit.
In case of using a metal sheet for meeting above mentioned safety
requirements it needs to be at least 2mm thick sheet of metal;
 It is strongly recommended any flammable objects (wood beams,
furniture, curtains and flammable liquids) to be placed on distance at least
1 (one) meter from the zone of intensive heat radiation. In cases that such
objects are near to the stove, you need to protect them with a layer of fireresistant insulating material. If the floor is made of flammable material
(wood) it is necessary in front of the stove to be placed protective sheet of
metal with size 300mm minimum;
 Before entering the stove in service you need to check the draught of the
chimney and to ensure that the stove is properly connected to the
chimney;
 Maintenance procedures of the stove should be performed by trained adult
persons, which have read and understood the user manual of the unit;
4.3. Installation process of the stove.
Installation procedure of the stove requires development of engineering
project for the heating system, prepared according to the acting local norms
and recommendations as follows:
Page. 22/61
 EN 14785:2006 – „Heating units for dwellings, utilizing wood pellets.
Terminology, requirements, testing and marking”;
 To the chimney;
 Fire prevention requirements;
 To the power circuit - EN 60335-1/1997- “Household and similar
electrical appliances – safety, Part 1 – General requirements”;
4.4.
Appliance positioning in order to achieve comfortable maintenance.
o Minimal distance of 500mm in front side of the unit and any wall
should be provided;
o Minimal distance of 150mm from the rear side of the unit and any wall
should be provided;
o Minimal distance of 600mm from the right hand side of the unit and
any wall should be provided, in order to guarantee easy access to the
stoves modules;
o Under the stove is required an non-combustible stand (layer).
o Minimal distance of 600mm above of the unit and any ceiling(wall)
should be provided, in order to guarantee easy access to the fuel’s
hopper, as well as enough room for cleaning purposes of the heat
exchanger body as well as fuel hopper charging;
o Minimum distance in which can be TEMPORARY placed flammable
materials is 1500mm;
EXPLANATION: The exact distances from any flammable objects and
materials must be determined after a consultation with a specialist when
are taken into count the exact positioning of the stove in the room and the
flammability index of the surrounding materials and objects;
During exploitation of the stove the outer services of the appliance get hot
and the surface temperature can exceed the safety limits and could cause
skin burns at contact. The zones with high surface temperatures are shown
in the figure below.
Page. 23/61
Zone 1
Zone 2
Figure 4.1. Outer view of hot air stove of series “Pony” with marked hot zones
which must be taken in count during exploitation (marked zones are with
temperatures exceeding the safe values and it is possible to cause burns at
contact);
EXPLANATION: The surface temperature of the marked Zone 1 can exceed
80 oC, while the temperature of the glass (marked as Zone 2) of the door of the
combustion chamber can rich 280-300 oC;
 Placing the stove according connection to the power supply: Place the
appliance so a free connection to a power outlet can be easily made
Page. 24/61
(230V/50Hz). It is prohibited the stove to be installed in room with power
supply system, mounted on the floor.
4.5. Connecting the stove to a chimney
Before connecting the stove to the chimney you must check if the chimney is
cleaned, with the required flow rate and if it ensures the required draught. Make
sure that the chimney is air tide in order to to prevent the possibility of flue
gases escaping. The use of heat resisting silicon is recommended. It is prohibited
the use of cement or cement based materials for packing the chimney. In case of
using an existing chimney it needs to be thoroughly checked for functionality
and safe work, because some untied places can cause flue gases to escape to
living area and to harm the health of the living creatures. In case of the existing
chimney not being air tide you need to fix so it will be safe to use.
ATTENTION: It is prohibited the direct exhaust of flue gases through a
wall. The use of chimney is obligatory. The chimney exhausts the flue gases
to a safe height away from the inhabited zone.
In cases of using external chimney (a chimney which is not a part of the
building and it is mounted independently to a side wall of the building.) you
must check the following:
 You must use pre insolated chimneys (so called “double pipe”),
mounted to the side of the building;
 In the base of the chimney you must install an opening for cleaning
and maintenance;
 The chimney must be well placed and mounted, it should be protected
from the influence of natural processes as storms, winds and rains.
Also it needs to meet the minimum distance from the highest point of
the roof.
EXPLANATIONS:
 It is recommended the stove to be placed as close to the chimney as
possible so you can minimize the number of used elbows and fittings;
 It is prohibited the use of the stove connected to a chimney already used
by another appliance. The stove must be connected to independent (single
duct) chimney;
 When installing/constructing the flue gas stack, you must check the
following:
o
The connecting channel must be with cylindrical shape. The diameter
of the tract must be equal or larger that the diameter of the exhaust of
Page. 25/61
the stove. The chimney and the tract must be well insulated in order
to prevent cooling of the smoke gases and decrease in the draught;

o
You must check the strength of the tract. It needs to be free of holes
or cracks;
o
The inside surface of the tract needs to be as smooth as possible. If
you use elbows they must be with the maximum possible radius of
curvature, not smaller than twice the diameter of the tract. In cases of
use of long curvatures they need to be with minimum difference
from the straight shape;
o
When building the chimney you need to make it easy for
disassembly for cleaning and you need to install condense tubs;
o
The exit cross-section of the chimney must be realized in a way
preventing entering of hail, snow or other. And also in event of
strong wind to prevent returning of smoke gases backwards to the
building;
o
The chimney needs to be wind-proof. The exit must be above the
highest point of the building’s roof. The exit section of the chimney
needs to be away of other buildings;
The automated hot air pellet stove of series „Pony” is different from the
stoves with manual fuel loading – the stove is equipped with flue gas fan
creating under pressure in the combustion chamber. The exit of the
chimney is with over pressure, this requires the chimney to be well packed
with heat resistant silicon (up to 250 oC). The connection with the
chimney must be done in a way that in cases of cleaning and maintenance
will not require to be removed. It is recommended the tract to be made
from stainless steel. (AISI 316) with minimum thickness of 1.0mm. The
diameter is recommended to be 80 or 100mm. It is also recommended the
use of pre insolated pipes (so called “double wall” pipes). The making of
doors, valves which could create resistance in the movement of the flue
gases is prohibited. The connecting pipe needs to be anchored. Also you
can use a flexible pipe. In cases of curvatures they must be with maximum
radios.
In the table below is provided information for the length of the connecting pipe
as function of its diameter.

Table 4.1.Main requirements to the tract connecting the stove with the chimney;
NOTE : the hydraulic loses (static pressure decrease) at fluid flow, convecting
through a 90o elbow are equivalent to the loses of flow in straight pipe with the
same diameter and length of 1meter. That’s why any curvatures, elbows, etc.
should be avoided if possible;
Example for calculation of the maximal length of the flue gases extraction
pipe and connecting it with the chimney:
 In case the connection requires installation of 3 ct. 90o elbows, then, the total
length of the connecting pipe is 4.5m;
 In case the connecting pipe requires two 90o elbows, then the third elbow
(from the example above) could be replaced with straight pipe and thus the
total length of the pipe could reach 5.5m (4.5 + 1.0m, instead of installing an
90o elbow). In the same way, in case only one 90o elbow will be installed,
then the total length of the piping could reach upto 6.5m;
 In case the connecting pipe has diameter of 100m, then it has to get another
transition element from diameter 80mm to the nominal diameter of 100mm,
along with T-shape elbow;
NOTE: the Т-shape element is used to form a zone, where the condensed water
vapor could be collected, formed at the heating-up process of the operating
mode of the stove . This T-shape element also allows deposition of fly ash
particles and allows easy access for cleaning purposes, without the need to
disassemble the chimney.
The chimney and the flue gas duct should be air tight (no loose
connections or cracks are allowed. The chimney, as well as the flue duct
Page. 27/61
connecting pipe should be insulated with mineral wool of thickness minimum
50mm and density upto 80kg/m3.

Table 4.2. Main requirements for construction of the chimney according to the
characteristics of the building’s roof;
 Connecting the pipe for fresh air for combustion in the stove with diameter
d=35mm. The pipe should not be directly connected to the outside
atmosphere. The air inlet needs to be close to the stove and the air must flow
easily through it. The air inlet must meet the following characteristics – to be
made from metal (steel) pipe or flexible house and to be well packed in the
connecting areas. The minimum diameter is D = 60mm, the outside end needs
to be with a screen (grill) preventing it from getting clogged. This end needs
to be protected from water getting in cases of rain or a float. It also needs to
be away from the chimney. In cases of not enough fresh air being supplied to
the room the concentration of oxygen droops and that can cause serious
danger for the health of living organisms. If these conditions are not followed
the heated area needs to be frequently ventilated. That will lead to increased
fuel consumption. In cases that the fresh air is supplied from different room
you need to provide save conditions for operation of the stove. It is
prohibited the premises from which is supplied the fresh air for combustion
to be used as living rooms. It is prohibited the premises from which is
supplied the fresh air for burning to be used for storage or work with
flammable gases or liquids. It is prohibited the pipe for fresh air for burning
to be connected to the ventilation system of the building. In the next table are
shown the main requirements for installing the pipe (inlet) for fresh air for
burning in the stove;
The pipe, which supplies fresh air for the combustion process of the stove has
diameter d=35mm. This pipe should NOT in any way be directly connected to
the fresh air supply duct of the stove.

and pellet stove , model “Pony PS9D”, which supplies hot air for heating
purposes to a neighboring room.
Page. 29/61
EXPLANATION : it is highly recommended to construct the hot air
distribution system with as minimal as possible length of the hot air duct, also
the number of the elbows should be kept as minimal as possible. The
recommended total length of a hot air convecting duct is 3 meters. In order to
get aesthetically view of the heating system, it most of the cases the hot air duct
is covered with a construction. This construction is designed from gypsum made
cardboard plates, the entire construction requires to be made by specialist. It is
also highly recommended to insulate the hot air duct, in order to minimize the
heat energy loses at the convection of the hot air through the duct, supplying
heat energy to the neighboring room. The end of the hot air duct should be
supplied with a air distribution control grid, which could be used to adjust the air
flow rate, as well as the direction of the air to the volume of the heated room.
ATTENTION :
 The presence of elbows in the hot air supply dust increases the hydraulic
losses and thus decreasing the hot air flow rate to the neighboring room.
In order to keep the air flow rate in optimal range, it is highly
recommended to keep the number of elbows, curvatures, as well as the
total length of the hot air supply duct as minimal as possible;
 The construction of the hot air supply duct should consider the local
conditions, i.e. the orientation and distance between the heated rooms,
also the length and the thermal expansion the hot air duct (especially if the
duct is made from plate (not corrugated) pipe), the presence of flammable
materials, and the fire safety regulations;

Entering the appliance in service.
ATTENTION:
 The unit should be installed, adjusted and verified ONLY by trained and
authorized staff;
 The finishing of the installation of the unit and the tests for functionality
must be noted in the warranty card. All the designated for that purpose
areas in the warranty card must be correctly filled;
5.1.
Basic fuel requirements.
 It is prohibited the use of fuel different than the specified by the producer;
 The fuel, pellet shaped, should be dry. The unit producer recommends that
the fuel should be stored in dry and well ventilated rooms;
 It is strongly forbidden to store the fuel in close region of the stove, the
minimal safety distance between the fuel and the appliance is 1000 mm;
 The unit producer recommends an optimal distance between the stove and
the fuel container to be at least 1500mm. It is recommended to store the
fuel in room, next to that, where the stove is installed;
 At the installation procedure of the unit, as well as the fuel storage one,
fire prevention recommendations should be considered;
EXPLANATIONS:
 The wood pellets need to be with regular cylindrical shape and smooth
outer surface. Their diameter should be constant along the length of the
pellet particle as well;
 The quantity of dust in the pellet bags needs to be as low as possible;
 It is recommended the pellets to be stored in bags, because they are
sensitive to humidity - they absorb moisture from the ambient air and as
result their mechanical durability will be significantly decreased, also the
combustion process is influenced and the pollutant flue gas emissions are
increased;
ATTENTION:
 The use of fuel which does not meet the above mentioned requirements
can cause:
o clogging of the burner and/or the flue gas tract of the stove;
o increased fuel consumption rate;
o lower thermal capacity of the stove;
Page. 31/61
o dirty glass of the burning chamber’s door;
o unburned fuel in the ash container;
o clogging the fuel feeding screw and blocking the fuel supply
channel;

Power supply of the stove
 The unit should be connected to the main power supply with the provided
connection cable, according to the safety rules and appropriate norms;
 The hopper should be filled with pellets, in order transport material by the
pellet feeding auger to the burner. It’s recommended to set the pellet
hoper lid closed;
EXPLANATION: For safety reasons it is recommended the refueling to
be done when the stove is stopped and cooled down. In cases of refueling
is needed to be done during work of the stove, you need to be careful the
pellet bag not to touch the hot surfaces, as the plastic could melt down;
ATTENTION: The producer is not responsible for damages or improper
work of the stove if fuel, which does not meet the producer’s requirements
is used. The producer is not responsible and does not cover the warranty
in cases of use of fuel which does not meet the requirements – for instance
bad quality pellets can damage the fuel feeding mechanism;
 The unit is connected to the main power supply with the provided
connection cable, the coupling is connected to the stove’s electric inlet
and the power plug is connected to grounded power outlet.
ATTENTION: In cases that the stove is too hot the power supply cable
can get melted/damaged in contact with the hot surface. The use of
melted/damaged cable is PROHIBITED;
5.2.4.
Turning ON the appliance.
 Turning on the stove in working regime is done by pushing button (4) for
a period of two seconds. In this regime the heating element is on (at the
same time the smoke fan is working and for some periods of time the
screw is feeding pellets into the burner). The heating element heats up the
pellets in the burner until they ignite. This process takes up to 15 min.
depending of the characteristics of the fuel and the ambient temperature;
 Use buttons (1) and (2) to set the desired temperature of the air in the
room, where the stove is installed;
 The desired power level of the stove is set by buttons (5) and (6);
 The adjustment of the air distribution to another room is made by a lever,
found in the front grill of the stove – valid for pellet stove model “Pony
PS9D” only – see figures 3.8 and 3.9;
Page. 36/61
EXPLANATION:
 In regime of igniting the fuel is activated a heating element, which is
placed on the right hand side of the burner, the heated air (from the
heating element is delivered in the bottom right side of the burner. The
heating element stops after a preset temperature of the smoke gases is
reached. This temperature is measured by thermosensor mounted on the
exhaust channel;
 During first startup of the stove or during a startup after the stove has been
stopped, because of lack of pellets, the startup procedure may be repeated ;
 The stove works according a preset operating algorithm realized by
specialized software loaded into the control module. The customer can
control and change some of the parameters;
 After the set-point of the air temperature in the room is reached, the
controller automatically switches to a minimum power;
 During first startup of the stove, it is highly recommended to ventilate the
premises, because is possible to accrue unpleasant smell of burning paint;
 Only for pellet stove model “Pony PS9D” : it is recommended to adjust
and control the air flow distribution by the lever after the stove has been
heated up and in steady-state mode (i.e. the stove is operating at constant
conditions and the room temperature does not change for long period).
Detailed description of the air distribution and heating another room is
shown on figures 3.8 and 3.9;
ATTENTION:
 During work the door of the stove needs to be completely closed,
otherwise escape of flue gases to the room can occur;
 During work of the stove, some surfaces get very hot. See figure 4.1. Do
not get burned. Keep the hot surfaces from contact with water or other
liquids, because that can lead to breakage or damage to the stove’s
modules. The producer is not responsible in cases of not following the
safety requirements or if the stove is used in inappropriate way from the
that described by the producer;
 The total closure of the hot air supply duct should not be allowed in any
way, in order to prevent stove’s overheating – valid for pellet stove model
“Pony PS9D”;

The producer preserves its rights to make changes to the setting and the
program of the stove, without being obligated to inform the end user.
EXPLANATION: The stove heats the premises by convection and thermal
radiation so it is easy to determine the power output by measuring the fuel
consumption, knowing the calorific value of the fuel and the efficiency of the
appliance. A sample for this approach follows :
Measuring the fuel consumption in regime of nominal thermal capacity (for 1
hour or shorter period – 15 minuets=1/4 hour)- mpellets=2.1 kg/h. Calculating the
instant fuel consumption rate, dividing by 3600 (1 hour = 3600 seconds) equals
m’pellets = 0.0005833 kg/s;
o Considering the calorific value of the fuel – Hpellets = 17.2 MJ/kg =
17200 kJ/kg – this is the calorific value of wood pellets. Also other
dimension can be used – the calorific value of wood pellets in kWh
4.77 kWh/kg;
o Considering the efficiency of the stove in regime of nominal thermal
capacity – ηstove=90%=0.90;

NOTE: - The ash content of the pellets does not change sensitively the calorific
value of the fuel, but it requires a specific construction of the burner. That is
why every fuel needs to tested before being recommended by the producer for
utilization in the stove;
Page. 41/61
5.2.6.
Set up of the stove according to the thermal power needed.
It is recommended in order to achieve optimal, reliable and efficient
operation of the stove, it has to be adjusted according the heat consumption of
the heated premises. That is why there are five different regimes (operating
modes, corresponding to different thermal capacities) : 1, 2, 3, 4 and 5 in the
appropriate regime the stove should work without the need of going to minimal
thermal capacity. The right choice of power level leads to economic and
efficient work of the unit.

to a neighboring room – valid for model “Pony PS9D” only.
The adjustment of the operating parameters of the hot air for neighboring
room heating purposes (the temperature and the air flow rate) is made by
changing the position of the lever, shown on figures 3.8 and 3.9, which controls
the air flow control flap, as well as the power level (i.e. the thermal capacity) of
the stove itself. Additionally one could adjust an air flow control grid, installed
at the end of the hot air supply duct of the neighboring room (if installed).
EXPLANATION: it is recommended however, to make final adjustment of the
air distribution system in small steps, in order to achieve the expected thermal
comfort levels in each of the heated rooms (make small changes and wait until
the heating system get stabilized).
5.2.9. Nominal operating mode of the stove.
After the stove is in nominal operation and the room is heated we can
assume that the stove works in nominal regime and we can perform the so called
“HOT TESTS”.
EXPLANATION:
 In nominal operating mode the stove periodically cleans the ash residue
in the burner. That is done by lowering the heat power to minimum (the
fuel flow rate is at minimum) and increasing the rotational velocity of
the flue gas extraction fan (thus air with increased flow rate is delivered
in the burner and that leads to full combustion of the char residues and
also is blowing away the remaining ash particles. The time interval
between cleaning is changed by a service parameter (i.e. only service
personnel can change it). During cleaning process the thermal capacity
if the stove is decreased;
 If the stove is used to heat rooms with low temperature less than 10 oC
it is recommended the stove to be at minimum power in order to easy
heat the room and to prevent thermal shocks to the hot surfaces of the
appliance;
 The optimal heat load to the materials of which the stove is constructed
is at power level [3]. It is recommended using it at this level in order to
increase the live-spend of the stove;
 Work on maximum power level is not recommended, as such operating
modes leads to increased operating temperatures and also to increased
temperature levels of the ambient air, which leads to specific
unpleasant odor/smell;
Page. 43/61
 At initial operation of the stove, it can emit vapors of the paints, as well
as other odors. This will happen only once, and does not lead to any
malfunctioning of the stove. It is strongly recommended to ventilate
intensively the room, where the stove is installed
ATTENTION: The air flow rate is crucial for optimal operation of the
combustion process, organized in the stove – when the air flow rate is less than
the optimal rate, then this insufficiency will result in incomplete combustion of
the fuel, as the supplied oxygen is less than required. When the air flow rate is
higher than optimal, the result will be unsatisfying as well, because the
excessive air will lead to low temperatures in volume for controlled combustion
domain and will result in incomplete combustion of the fuel’s volatile gases,
released by the combustion process. That’s why the stove requires certain
amount of air for efficient combustion – see the technical data table of the init
for details;
NOTE: If the flame is dark in color (due to lack of oxygen) that means that the
burner needs cleaning of the ash residue, as well as char particles, in order to
allow the optimal air flow rate through the burner.
5.3.
Adjustment of the thermal capacity of the stove.
The adjustment of the thermal capacity of the stove is done by buttons (5) and
(6) from the interface module or by the remote control. There are 5 different
levels , the range is from [1] to [5] where [1] is minimum and [5] is maximum.
The recommended power level is [3].
EXPLANATION: If different (than specified in requirements of the stove) fuel
is used that can influence the power of the stove. It is obligatory the utilized fuel
to meet the requirements of the producer.
5.3.1. Decreasing the thermal capacity of the stove
Is done by pressing button (5), when pressed it decreases the power level
by step of 1.
NOTE: The minimum power level is [1].
5.3.2. Decreasing the thermal capacity of the stove
Is done by pressing button (6), when pressed it increases the power level
by step of 1.
NOTE: The maximum power level is [5].
Page. 44/61
5.3.3. Adjustment of the thermal capacity of the hot air, supplied to
the neighboring room – valid for model “Ponu PS9D” only.
The adjustment of the hot air flow rate, as well as its temperature, requires
manual adjustment of the position of the lever, which controls the air flow
distribution. The air control lever is shown on figures 3.8 and 3.9. In
principal the variety of heating systems is quite a lot, so in this guide only
basic recommendations and directions of the thermal capacity adjustments
are given. The appropriate and precise adjustment of the hot air
distribution is matter of experience at construction as well as operation of
such type of heating systems.
5.4.
Stopping the operation of the stove.
Stopping the stove is done by holding button (4) for few seconds. Then
the stove goes from working operating mode to a stand-by mode. That is
realized by stopping the fuel supply module (the transport auger), the remaining
fuel is burned and at the same time the stove cools down. The flue gas fan stops
after a predetermine time passed and the stove goes into stand-by mode. In cases
that operation of the stove is not required for a long period of time, it is highly
recommended to clean thoroughly to ash residue.
ATTENTION: In case that the stove will not operate for a long period of time,
then the heat exchanger should be thoroughly cleaned from the deposited ash.
The deposited on the metal surfaces ash acts corrosively on the carbon steel
surfaces, which will lead to a decrease of the lifetime of the stove’s main
modules – heat exchanger, as well as the burner. It is obligatory to perform
service procedures and preventive observations of the unit by trained service
personal only as well as thorough cleaning at the end of the heating season.
Completing these requirements will ensure long exploitation duration of the
stove and its high efficiency and reliability.
5.5.
Cleaning the stove
In order to maintain high efficiency and reliability of the stove the regular
cleaning of the accumulated ash residue is obligatory. The ash residue is a
function of the mineral mass content of the pellets.
Before cleaning the stove it needs to be stopped, cooled and disconnected
from the power grid.
The cleaning of the ash residue is done manually, by a brush or a special
vacuum-cleaner, or appropriate device. It is recommended after cleaning the ash
to be deposited to a designated for that purposes place;

„Pony”;
EXPLANATIONS:
 The cleaning of the stove’s burner is done with appropriate tools. The
main goal is to remove all char residue, slagging and fouling and to ensure
free passage of the air used for combustion. After cleaning the burner
make sure that it is positioned correctly. You may use the opening for the
heat element for guiding point. It is also recommended to check and clean
the channel for the hot air used for ignition;
Page. 47/61
 The cleaning of the burning chamber is done when the stove is completely
cooled. It is done by vacuum-cleaner. Make sure that the ash is
completely extinguished. Be careful not to put the vacuum-cleaning
appliance on fire;

The cleaning of the ash from the combustion chamber is done when the
guiding plate is removed. Use the hangers of the guiding plate in order to
detach it – pull the hanger and lift the plate, then pull towards the stove’s
door and remove it. Use brush to thoroughly clean all heat exchanging
surfaces from the deposited ash and char particles;
 The cleaning of the external metal covers in done only with wet soft
towel, the use of any organic dissolvent is prohibited, as its usage can
cause a damage to the paint;
 The cleaning the ash and char deposits off the glass is done when the
stove is cooled down to room temperature, it is recommended to use paper
sheets, user news paper, paper napkin or any appropriate material, then
use a proper glass cleaning agents;
 During maintenance be careful not to damage any gaskets. If needed a
gasket has to be changed;
 For model “Pony PS9D” only – it is highly recommended to make
thorough cleaning of the heating system at the end of the heating season,
as the hot air duct could have accumulated certain amount of dust and/or
other particles;
 After the end of each heating season the stove needs to be completely
cleaned from ash. The cleaning of the chamber in front of the smoke fan
is done after the unscrewing the fixing screws at the front cover (in the
lower zone of the stove) then door is taken out. Next remove the fixing
screws for the valve of the flue gas tract. After cleaning assemble the
stove in the reverse way ;
ATTENTION: The yearly maintenance and cleaning is necessary in order the
stove to function effectively and is obligatory condition in terms of warranty.

5.6.
Turning OFF the stove.
Turning OFF of the stove is done in accordance to the previous point of
the manual after that it is possible to disconnect from the stove from the power
supply.
 Emergency stop of the stove.
During exploitation of the stove it is possible to arise situations when the
stove goes in regime of failure. Some of these conditions are detected from
the control module and automatically preventive actions are taken. Also on
the display is shown a massage which informs the customer for the type of
malfunction.
In case failure the end user has to check the meaning of the alarm massage
shown on the screen and proceed with appropriate precaution actions.
Page. 49/61
ATTENTION : In situation of failure - overheating of the stove, the
controller automatically enters the stove in fading mode and stopa after
that, by this action the power output is lowered smoothly. The most likely
reason is dirty (the ash deposition in not cleaned) heat exchanging surfaces
leading to increased temperature of the flue gases or decreased capacity of
the air convecting fan.
After the stove cools down it is needed to determine the reason of the
malfunctioning and if necessary get the help of authorized service.
5.7. Showing and teaching the end user about the maintenance and
adjustment procedures.
It is necessary to show and teach the end user the maintenance procedures for
operating the stove efficiently and keep its reliability in high degree order. Also
the service person should demonstrate and teach the end user how to change the
operating parameters of the stove’s control module in order to operate the unit in
different modes and thermal capacities, according to the local heat consumption
rate:
 Fuel hopper charging – the fuel is poured out in the hopper of the
stove and the hopper’s cap should be closed in order to prevent
uncontrolled air penetration to the burner through this section;
 Ash cleaning procedure – it is recommended to clean periodically the
ash residue (at least once per day) Covering this requirement will
ensure effective heat exchanging process and will sustain optimal
operating conditions of the stove;
 For model “Pony PS9D” only – the way to adjust the air
distribution flap and to control the hot air flow rate, supplied for
heating purposes to a neighboring room – it is preformed by
adjustment of the air control flap, installed in a air distribution control
module of the heat exchanger. One can use the adjustable air control
grille , it such device is installed at the end of the hot air supply duct;
ATTENTION: regular cleaning of the ash residue, deposited on the heat
exchanging surfaces of the stove will ensure long-life reliable exploitation
period, economic and efficient performance of the unit;
5.8.
Safety and unexpected risks
Risks could arise at the exploitation of the stove:
The hot air pellet stove of series „Pony” is designed according to the
safety requirements of the operating European standards and norms.
Page. 50/61
However safety and unexpected risks could arise in situations like
following:
 Hot air pellet stove of series „Pony” is operating incorrectly;
 The unit is installed by unauthorized/unqualified personal;
 For model “Pony PS9D” only – the hot air supply system is
constructed and designed, not following the requirements, described in
this user manual;
 The safety instructions, described in this manual are not followed and
fulfilled;
Unexpected risks:
The unit is designed and produced according to the requirements of the
operating EU safety norms. However, in spite of that possible risks are
considered as a result of the operating process of the stove, it is possible to arise
risks as follows:
 Fire expansion risk, caused by falling out small smoldering hot particles
out of the combustion chamber at door opening (also char particles).
That’s why it is obligatory to operate the stove at closed door only, or the
combustion chamber’s door should be opened when the stove is cooled
down;
 Cauterization risks, caused by high temperatures, as a result of the
combustion process in the combustion chamber and/or direct access to the
front door of the combustion chamber (see figure 4.1), at manual cleaning
processes of the surfaces of the burner and/or combustion chamber, or ash
residue cleaning, accumulated in the ash tray or any unburned fuel
material, smoldering in the ash tray;
 Electrical shock risks at indirect contact. The stove is connected to the
power circuit and its operating modules are separated in specialized
electric control box, equipped with required protective and short-circuit
preventive devices. It is obligatory to perform stove ground connection by
authorized personal/technician;
 Fingers injuring risks at opening/closing the doors/caps of the stove at
maintenance and cleaning process of the unit. It is recommended to use
appropriate individual resources for self-protection;
 Suffocation risks due to insufficient chimney draught or untied spots in the
smoke gas tract poison gas leaks are possible;
